Common to All Models

  The indoor unit and the wireless remote control are equipped with 

indoor temperature sensors. The sensing of indoor temperature works 
via one of them.

  When the unit is shipped, it is set to the indoor unit, but to switch to 

the remote control, press the sensor button (diagram at right) inside 
the remote control’s cover and then check to make sure that Main 
Sensor on the LCD screen goes off.

<Note> 

Even when the sensor switch has been set to the remote 
control, if the unit does not receive any room temperature 
data from the remote control for ten minutes, it automatically 
switches back to the indoor unit sensor, so be sure to install 
the remote control facing the receiver.
